Suppose a living plant cell has ψ = ψ_S = -0.5 MPa. Also suppose that the plant cell is placed into a beaker filled with a solution for which ψ = 0. What will the cell then do?

Question

Quizplus · Accepted Answer

The cell will take up water until the pressure potential within the cell, ψP, is equal in magnitude but opposite in sign to the solute potential outside the cell, ψS. This equilibrium point is referred to as the cell's turgor pressure, and in this scenario, it would lead to an increase in the magnitude of the pressure potential (ψP) and a positive turgor pressure, preventing further water uptake. Therefore, only option B accurately describes the behavior of the cell in this scenario.
